Lessons learnt from my failure. Launched my product one week ago

One week back i released my product . Voblet - A better way to send,organize and share links. Website : https://voblet.com Explainer video : https://www.youtube.com/watch?v=z0q6ZiiC2Do I worked on this for almost 10 months.I expected it to be a big hit and thought people will start using it when they see the video. But it didn't happen. I failed to gather interest, these are some of the lessons learnt. 1) Explain your product in one interesting line When you post about your product in producthunt, reddit, hackernews, twitter etc. You should be able to get people interest with just your one line.No body has time to read your description and watch explainer video. When someone asks about your product and you failed to get his attention in one sentence.I think you should revisit your product and make it better and strong in at least one aspect. 2) Have at least one big differentiating feature If you have a competing product which is already popular.Doing small improvements will not make users install your app. You product should be very good in at least one thing than your competitors. Making things better is not sufficient.You can build user base on that and keep improving. 3) Have tools to get info on user behavior (Google analytics etc) For your initial launch, you will spend more time on writing code and making the functionality work.After the launch to make improvement knowing user behavior is important. Spend more time on gathering all the events,user interactions using google analytics. Have metrics based on your server logs etc. Next steps for me: Back to zero.Working hard in making improvements .Will launch my next version in few months with some big changes. Please leave your feedback on my product if you can . If you want to add any things to the above list please comment,it will be helpful :)
